ControllerExtension.use(EditFlow) with typescript does not work

shf — Fri, 14 Mar 2025 10:21:47 GMT

Hello,

I'm using typescript in my Fiori app and like to use EditFlow extension . I have a problem in initiating the EditFlow extension .

import ControllerExtension from "sap/ui/core/mvc/ControllerExtension"; import EditFlow from "sap/fe/core/controllerextensions/EditFlow"; import Controller from "sap/ui/core/mvc/Controller"; /** * @namespace paltr.core.configsystemkind */ export default class SetSystemKindsTitlesCustomAction extends Controller { private editFlow: EditFlow; public onInit(): void { this.editFlow = ControllerExtension.use(EditFlow); } .... }

I'm not using the Babel plugin, I'm using the ui5-tooling.transpile version 3.7.2 instead as described in the Fiori documentation section "Assigning controller extension" Using Controller Extension - Documentation - Demo Kit - SAPUI5 SDK

The mention "npm update" was executed.

My issue is ControllerExtension.use(EditFlow) throws the error "

Argument of type 'typeof EditFlow' is not assignable to parameter of type 'new () => EditFlow'.

Cannot assign a 'protected' constructor type to a 'public' constructor type.".

How do I call the extension correctly in typescript?

I have used the EditFlow with TypeScript as the example below:

this.base.getExtensionAPI().getEditFlow()
